Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018446, here are decompositions:

7 + 1018439 = 1018446
17 + 1018429 = 1018446
89 + 1018357 = 1018446
109 + 1018337 = 1018446
137 + 1018309 = 1018446
193 + 1018253 = 1018446
199 + 1018247 = 1018446
223 + 1018223 = 1018446

Showing the first eight; more decompositions exist.
